andromedae a. sudarsky had, on the assumption that the planet is similar to jupiter in composition and that its environment is close to chemical equilibrium, predicted upsilon andromedae b to have reflective clouds of silicates and iron in its upper atmosphere. the cloud deck instead absorbs the sun's radiation ; between that and the hot, high pressure gas surrounding the mantle, exists a stratosphere of cooler gas. the outer shell of dark, opaque, hot cloud is assumed to consist of vanadium and titanium oxides ( " pm planets " ), but other compounds like tholins cannot be
